I'm going to try an upgrade from 11.2 to 11.5 on a couple of BIG-IP 6900 in active/standby.   Does anyone know if the traffic group would keep working between the two different version?   In th...

    Correct. I'll be upgrading our production LTMs next week in almost the same fashion, except we're going from v11.2.0 to v11.4.1. We also have 6900s in an active/standby pair.

     

    Every time we've upgraded our LTMs in the past (10.2.1 to 10.2.3, 10.2.3 to 10.2.4, 10.2.4 to 11.1.0, 11.1.0 to 11.2.0), we've done it in this fashion. Never had an issue.

     

    Ensure your configurations are synchronized between the two units before you start and you should be fine. Oh, and be sure to re-license both units before initiating the new code installations so you don't encounter licensing issues after booting into v11.5.

Hi Cory, just a little follow up to let you know that the upgrade procedure worked fine. It may be useful to share that when working with 2 different versions (minor) while the traffic-group kept working flawless the sync db went in disconnected state (as expected). So during the upgrade procedure a slightly intimidating black "disconnected" message appear on the right top of the screen instead of the familiar "Sync" or "Changes Pending". Don't worry this will diasappear as soon as both boxes are upgraded to the same version, and have no impact on the active/standby switchover. Thank you again for you valuable input.
